It’s hard to believe that it’s been nearly a month since my last post. Time flies when you’re having fun in Australia.

On the big trip around New Zealand in January, one of our first significant stops were the famous Moeraki Boulders, a few kilometers north of Dunedin on the South Island’s east coast. The Moeraki Boulders aren’t exactly spectacular like a lot of New Zealand’s mountain scenery, but they’re still awe-inspiring in their own way. These boulders (and other similar boulders around the world) are concretions that were formed when minerals (calcite) seeped into the interstitial spaces between mud and sand grains and “hardened.” Don’t ask me exactly why these minerals hardened; similarly, don’t ask me why these concretions are so nicely spherical in shape. Just chalk it up to some of the wonderful geological mysteries of Nature. (Yes, I know that I’m a guy and that I’m supposed to know everything, but let’s just leave it at that.) I’m not going to write a whole lot this time and just leave you to enjoy the gallery at your own pace.
